Unrrnn STATES BENJAMIN B. BEERS, OF BRANOHVILLE, CONNECTICUT, ASSIGNOR OF OXF- HAIJF TO NATHAN COUCH, OF SAME PLACE.

BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 359,954, dated March 22, 1887. Application filed September 1, 1886. Serial No. 2l2.369. (X model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN B. Bonus, a citizen of the United States, residing at Branehville, in the county of Fair-field and 5 State of Connecticut, have invented certain new and useful Improvements in Butter-forkers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in IO the art to which it appertains to make and use the same.

My invention has for its object to simplify, strengthen, and cheapen the construction of this class of machines, and at the same time to greatly improve, their mode of operation. \Vith these ends in view I have devised the novel construction of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to indicate the several parts of the machine.

Figure l is a central section of the device complete, showing the manner in which it is attached to the table; Fig. 2, a plan view, and

- Fig. 3 is a side elevation.

1 denotes the frame-work; 2, braces for holdiug the parts firmly together; 3, a central standard firmly secured in the frame-work; at, carrying-rollers journaled on pins projecting 0 from brackets 5, and 6 a circular trough or table which rests upon the carrying-rollers. Any number of carryingrollers may be used, although in practice I have found four to be quite sufficient. I preferably provide the 3 5 trough or table with a circular groove, 7, near its outer cdge,in which the rollers rest. The bottom of the circular trough or table is preferably inclined toward the center, as clearly shown in Fig. 1, in order to permit the buttermilk to 0 pass off as fast as it is worked out from the butter. At the center of the trough or table is an opening, 8, through which the central standard passes, and also a central sleeve, 9, which projects upward from the center of the receivingtank l0. Thesleevc passes over the standard and fits it closely, and projects up above the bottom of the trough, there being ample space between the sleeve and the edge of opening 8 to permit the buttermilk to run through. It will thus be seen that all of the escaping buttermilk must pass down outside of the sleeve and into the tank. The tank is held firmly in position by the central standard, but

is readily removable. The sleeve prevents any of the buttermilk from running down thestand- 5 ard, and thus smearing thewhole machine. 11

is a roller having working-blades 12. The inner end of this roller is journaled in the central standard, and the outer end in a standard, 13. At the outer end of the roller-shaft is a crank, let. Rotary motion is imparted to the trough by a pinion, 15, on the roller-shaft, which engages a circular rack, 16, upon the trough. In practice I preferably make the working-blades of even width from end to end, and so arrange the roller that the edges of the blade are substantially parallel with the inclined bottom of the trough, as is clearly shown in Fig. 1, it beingof course necessary that the outer endof the roller should be journaled considerably higher 0 than the inner end. As the mass of butter passes under the roller the working-blades press out the buttermilk, and of course spread out the mass in all directions.

As it is desirable that the position of the 7 mass should be changed as much as possible during each revolution of the trough, so that the blades will not strike in the same place every time, I have provided a guard, 1.7,which is carried by the central shaft, and a guard, 8o. 18, carried by a standard, 19, diametrically opposite to standard 13. The action of these two guards is to pile up the mass of butter midway between the central standard and the outer edge of the trough, so that each time it passes under the roller the blades actina different place. Both of these guards are made readily detachable, guard 18 being secured by pins 20, which engage a slot in the top of standard 19, and guard 17 being adapted o to slip on over the central standard, a pin, 21, engaging a groove, 22, in the standard, so that the guard is prevented from turning.

One of the most valuable features of my improved machine is its cleanliness and the case 9 5 with which all of the parts may be removed in order to be washed. In use there is no spattering whatever, the butter coming in contact only with the roller, the trough, and the guards, and the construction being such that the but- 109 termilk is all caught by the tank and does not run all over the machine. The roller is journaledin the simplest manner possible. The inner end is engaged in. an opening, 23, in the central standard, and the outer end of the shaft rests in a groove, 24, in standard 13, a crosspin, 25, holding the shaft firmly in position in the groove.

In order to remove the roller,it is simply necessary to withdraw the pin and lift it out. Guard 18 is removed by simply lifting pins 20 out of the slot. As soon as the roller is removed guard 17 may be lifted off from the central standard, likewise the trough, and then the re ceiving-tank, which rests upon a projection or support at the bottom of the central standard.

Heretofore, so far as I am aware, butter- WOIRGIS of this class have either been provided with legs or standards for supporting them. or elsewith clamping devices with which they have been secured to a table. I wholly do away with standards and clamping devices, and provide for holding the machine upon the table by means of two inwardly-turned clips, 26, which are placed at the outer ends of two of the cross pieces of the framework next to each other-that is, so that the clips will face inward at right angles to each other.

The device is simply placed on the corner of the table and pushed forward until thetwo clips engage the two angles of the table-edge, as clearly shown in Fig. 3. One of these clips is of course placed at the same side of the machine as the crank, so that when the machine is in use the action is to press the machine farther on the table, rather than to draw it off. I have found in practice that this simple means of holding the machine in place is as perfect in operation as could be desired.

It will of course be understood that the details of construction may be considerably va-i ried without departing from the spirit of l my invention.

I claim- 1. The central standard having groove 22, the rotating trough or table having a central. opening, and the working-roller, in combination with the receiving-tank having a central.

sleeve adapted to pass over the standard and project through and above the bottom of the a roller having working-blades journaled in M said standard and in a standard, 18, and a guard, 17, having a pin engaging groove 22, as described, and for the purpose set forth.

3. The combination, with the central standard having groove 22, standard 19, having a slot at its top, the rotating trough, and the worker, of a guard, 17, carried by the central standard and havinga pin engaging'groove 22, r

and a guard,18, having pins 20, which engage the slot in standard 19, as and for the purpose set forth.

In testimony whereof I affix my signaturein presence of two witnesses.
